Draw a diagram! Lets say the width is x, then the length must be 2x.
Area = length x width
2x x x = 8sq meters
2x^2 = 8
x^2 =4
x = √4
x = 2
we found the width the length is two times the width, making it 4 meters.
The way to find the area of a triangle is A=

if the base is 3 feet longer then the height we can write it like this B=H+3
now we can add it to our area equation
20=

20=

40=

+3H
10

=

h=3.2ft
The second one is your answer
Answer:
You are right!!
Step-by-step explanation:
- 8 = 4 x (- 2)
- 16 = 4 x (- 4)
- 24 = 4 x (- 6)
